New iPhone 4 and iPod touch appear in Apple's inventory system

9to5Mac posted a story that two new iPhone SKUs that have showed up in the Apple inventory system.

The catch is that these two SKUs are actually marked as tweaked iPhone 4s. The new device’s codename is N90A and this represents very minor changes from the iPhone 4 – which is the N90. In fact, this may be an iPhone 4 – an 8GB version as previously rumored. It is very possible that the two SKUs mean black and white models, but that is unconfirmed. We don’t think Apple’s next-generation iPhone – coming next week- would be labeled as an N90A – as it includes major internal hardware upgrades that would typically constitute a new codename. Additionally, the iPhone codename of N94 has appeared in the iOS SDK on numerous occasions.
